MOP AND HANDLE THEREFOR.

Application filed June 18, 1924. Serial No. 720,233.

To all whom it may concern:

Be it known that I, EDWARD PRENDER- eAs'r, a citizen of the United States, and resi dent of the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Mops and Handles Therefor, of which the following is a specification containing a full, clear, and'eXact description, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to improvements in mops and handles therefor and has for its primary object, the construction of such a device wherein old rags or towels or any fabric may be used in making the mop in a simple and easy manner, and the mop fabrics or rags may be removed for cleaning.

In the drawings Fig. 1 is a top plan view with parts broken away;

Fig. 2 is a transverse section takenon the line 2.-2 of Fig. 1 looking in the direction of the arrow;

Fig. 3 is a fragmental sectional view of a modified form of mop head.

Referring to the drawings-4c, 5, 6, 7 and 8 indicate wooden. slats out of which the mop head is constructed. These slats are preferably rectangular in cross section and may be made out of any material, preferably wood, and length and number of slats suflicient to form a mop head of the desired size. Located in each end of the slat 4 is a metallic pin, peg or prong 9, which is provided with a sharpened end 10 on one end so as to be readily inserted through the material out of which the mop is fornr'ed, and on the opposite end with a slotted head 11, and for a short distance with screw threads 12 on which a nut 13 is located. The nut 13 is angular and located in an angular recess 14; so as not to turn when the prongs 9 are turned. The prongs 9 may be turned by means of a screw driver so as to completely tighten the prongs in the slat 4. The prongs 9 pass through openings in the slats 5, 6 and 7 and into a recess or hole 15. In other words, the prongs do not pass entirely through the slat 8, the ends are protected.

Located in each end of the slat 8 and fastened in the same way, are prongs l6 spaced This bolt 21 is apart-from the prongs 9. In other words, each slat, 4 and 8, is provided with similar prongs or pins secured in place in the same way. The slat 4 carries a pair of prongs, and the slat 8 carries a similar pair of prongs.

In Fig. 1 I have shown my mop made up and held in position by the mop handle or holder, this mop holder comprises a jaw 17 provided with a pair of hooks 18, each of which is provided with a sharpened point 19 which is adapted toengage the forward slat intermediate its top and lower edge. Formed integral with the jaw 17 and intermediate the hooks 18 is an upstanding lug 20 provided with an angular opening through which a tightening bolt 21 passes.

provided with a squared portion 22 which is adapted to be seated in the angular opening of the upstanding lug 20. This bolt 21 is held in position by means of a bent over lug 23 against the bolt head 24.

Formed integral with the jaw 17 and in a rearwardly inclined position are corrugated ears .25, these ears are provided with an opening 26 through which a bolt 27 provided with a thumb nut 28, may be inserted. This clamp 17 is also provided with an upstanding lug 29 provided with an opening through which the bolt 21 passes. 30 indi cates a companion clamp which is also providedwith a pair of hooks 31 which are provided with inturned sharpened points 32 adapted to engage the outside face of the rearward slat out of which the mop head is formed. Struck from the clamp 30 is a pair of upstanding ears 33 and 34 through which the bolt 21 passes. It will thus be seen that the bolt 21 has four bearings, two in each clamping member.

The bolt 21 has a screw threaded end 35 on which a wing nut 36 is applied for tightening up and drawing the jaws toward each other.

Mounted 011 the corrugated ears 25 is a handle socket 37 in which the handle 38 is fastened. The handle socket 37 is provided with. a pair of corrugated extensions 39 in which openings are formed for passing through the bolt 27, and by means of this bolt 27 the handle socket or more specifically the perforated extensions 39 thereof, are fasthis connection that the tened to the upstanding ears 25. This socket handle 37 and consequently the handle 38 may be adjusted up and down by loosening and tightening the nut 28. In other words the handle 38 is adj ustably mounted relative to the mop head.

In Fig. 3 I have shown a slightly modified way wherein the pins for holding the mop head slats together pass entirely through the slats and are provided withsharpened ends and screw threads 40 on which wing nuts 41 are mount-ed. This construction is preterablv employed in the making of a relatively large mop head for the reason that additional means are employed for holding the slats tightly together, tor, it will be observed in Fig. 1, the slats or mop head are held togetherby the clamping jaws, and in F 3 they are intended to be held together not only by the clamping aws, but also the wing nuts 41.

In making; up a mop accordingto my improvement, I take any desired material and wrap it once around the slats or ottener 1f desired, inserting the pins carried by the slats therethrough .and after each slat has been thus wrapped with the mopping material, they are assembled together as illustrated in Fig. 1, and then the clamps 17 and 30 are applied and tightened up by means of the wing nut 36. 7 It should be noted in purpose of wrapping the mopping material around the slats is to thoroughly cover and enclose the same and prevent the marring of the woodwork.

It will be noted in this connection that in practice the mopping material is longer than the slats so as to prevent the ends of the slats from coming .in contact with the woodwork.

From the foregoing description it is obvious that in place of using the mop head as illustrated and described, I may apply the clamping members and adjustable handie to various kinds of scrubbing brushes.

In the construction shown however, the clamping members or jaws '17 and 30 merely form a part of the mop head for the reason that by this adjustable clamping means the various slats on which the mopping material is applied, are held together.

Having fully described my invention, what I claim is 1- 1. A mop composed of a series of slats adapted to lie side by side, mopping material wrapped around each slat, a sharpened pin located in each end of the outer slats and adapted to pass through aligned openings in the intermediate slats, said pins pointing in opposite directions and being spaced apart from each other, the said outer slats being provided with depressions intermediate their ends, an adjustable clamping mechanism provided with jaws located in said depressions and engaging the same intermediate the top and lower edge of the slats, a bolt for drawing said jaws toward each other and against the slats for holding the same firmly together, and an adjustable handle pivotally carried by said clamping mechanism.

2. A mop comprising a series of slats rectangular in cross section, and comprising a pair of outer slats and intermediate slats formed with aligned holes therethrough, a sharpened prong; provided with a grooved head and screw threaded adjacent the head, and a nut thereon located in each end of the outer slats and being spaced apart from each other and adapted to pass in opposite directions throughv the holes formed in the intermediate slats, mopping material located entirely around each of the slats and of sutit cient length to protect the ends of the slats, said mopping material having the prongs passing therethrough, a clamping jaw provided with a pair of bearings located against each outer slat, a bolt located in the bearings of said jaws, and a wing nut mounted on said bolt for removably clamping the jaws against the slats, an adjustable handle pivotally mounted on one of said clamping jaws, and means for securing said handle in adjusted position.

In testimony whereof, I have signed my name to this specification.

EDWARD P'RENDERGAST.
